To all whom it may. oonoetmi.

-Be it: known that I lhznsumcn 6. Sim, a;

of Cleveland; county of Gfuyahoga, and, States of" 0hi'o have invented a new and'useiul Improvement, in. inking ieehanisinfor Printing lihlesses, oti which the following is a speeiticatioln'the principleofthe invention being; heneine plaine-dand the :hest'niode in which il hzwecontemplated applying; that principle; so as to 'distinguishit from other inventions. ,i

The present improvements relate. smote 'particularlytosorealled Vibrator rollers for distrlbuting they-ink-non; the rollers that directlyfl CQljLliZlOlL With the "disk :and: torn; in

In said annexed drawing:

Asa result-of the tone going constructions it will be seen that the: members 15 are not only free to shit't longitudinally of the respective saddles= but also vertically, thus allowing the necessary: amount of i i eedoin to the bmies 10 whereb the roller 20, supported on the spindle 11. next to he described may find ""self, i, e,

vided with a collar 21 that is both rotatably and longitudinally movable on said spindle 11, while at its other end said roller is provided with an internally threaded nut that engages with an externally threaded sleeve 28 non-rotatably secured to spindle 11 by means of a pin 24-, a collar 25 fixed to said spindle at the lnner end of the sleeve serving additionally to hold the same against longi- Said threaded sleeve 23 tudinal movement. projects a short distance beyond nut seems the corresponding end of roller 20 when the latter .is in the extreme right-hand position, and in this position a stop 26 on said nut engages with a pin 27 that projects radially from said sleeve. The inner end of nut 22 is provided with a reversely directed stop 26 that is adapted to engage with a cor responding radially projecting pin 27 on collar 25, when the nut, by reason of rotation of the roller 20, has been moved to the inner end of threaded sleeve 23. i

The outer endof sleeve 30 is also formed with one or more beveled teeth 28 that are adapted to engage corresponding notches 29 end and the adjacent box 10. This lastmentioned sleeve is free to partake of limited movement longitudinally. of spindle 11, butis held against rotation with respectto-said spindle by means of a key 31 projecting inwardly from box 10 and engaging a notch 82 in the adjacent end of said sleeve. The latter is furthermore hollowed out for a portion of its length to form a housing for a compression spring 33, the outer end of which appears against said box 10 so as to normally press said sleeve 30 towards threaded sleeve 23.

From the foregoing construction it will be seen that with the parts in the position shown in Figs. 2 and 1, i. e.,'when the sto 26 on nut 22 strikes the pin 27 on threade the roller 20, and spindle 11 will at the same time be caused to revolve in journal box 10,

such rotation of the parts in question causing the sleeve 30*to be longitudinally displaced outwardly, i. e. to the right, as tooth 28 rides out of notch 29. Such rotation may occur through one or more revolutions with-,

and at the same time move longitudinally of the axis of spindle 11 until stop 26 engages the pin 27 on collar 25. Then the same action with respect to sleeve 30 will occur as before. 7 Depending upon the length of threaded sleeve 23, it will be seen that any amount naled.

sleeveg 23, the latter willbe caused to revolve on said saddles, an

is reached the roller will continue to row,

tate without. further longitudinal movement. It will also-be seen that the roller 20 is at all times held properly centered against the rollers d wherewith it contacts, and under a uniform pressure throughout its length, by reason of the floating mounting of the boxes 10, in which the ends of spindle 11 are jour- I gards the mechanism herein disclosed, pro'-- vided the means stated by any of the following claims or the equivalent of such stated means be employed.

I therefore particularly point out and distinctly claim as my invention 1. In mechanism of the character described,

I, the combination of a pair of inking rollers in a second sleeve 30 interposed between such adapted to contact withthe inking disk and form of a printing press, saddles for the respective ends of said rollers, an ink-distributing roller mounted above and in contact with said first-named rollers, and mountingsfor the ends of said ink-distributing roller, including a transverse member on each of said saddles provided with a bearing for the correspondingend of the spindle of'said roller, said memberbeing formed with elongated slots, bolts on said saddle passing through such slots, and springson said bolts pressing downwardly on said member, whereby'the latter is free to move both transversely and vertically relatively to said saddle.

2. Tnmechanism of the character described,

the combination of a pair of inking rollers adaptedto contact with the inking disk and form of aprinting press, saddles for the respective ends of said rollers, a spindle rotatably journalcd at its respective ends on ink-distributing roller iounted on said saddle so as to contact with said first-named rollers, an externally threaded sleeve fixedly secured to said spindle, an

internally threaded collar on said roller engaging said sleeve, elements carried by said spindle and roller, respectively, adapted to interengage when said collar reaches either end of said sleeve and thereby non-rotatively lock said roller to said spindle, and a second sleeve on said spindle between the outer end of said first sleeve and the adjacent saddle. said second sleeve being longitudinally movable of but held against rotation with said spindle, and means housed within said second sleeve pressing the same against said Such boxes, furthermore, maybe first sleeve for holding said spindle against rotation until said interlocking elements upon the roller and spindle become engaged at either end of the line of travel of said adapted to contact with the inking disk and form of a printing press, saddles for the respective ends of said rollers, a spindle rotatably journaled at its respective ends on said mounted on said saddle so as to contact with said first-named rollers, an externally threaded sleeve fixedly secured to said spindle, an internally threaded collar on said roller engaging said sleeve, elements carried by said spindle and roller, respectively, adapted to saddles, an ink-distributing roller interengage when said roller reaches either end-of said sleeve and thereby non-rotatively lock said roller to said spindle, and a second sleeve on said spindle between the outer end of said first sleeve and the adjacent Saddle, said second sleeve being longitudinally movable of but held against rotation with said spindle and the contacting ends of said sleeves being formed with complementary beveled teeth and recesses, and a spring pressing said second sleeve against said first sleeve, whereby said beveled teeth and recesses will serve to hold said spindle against rotation until said interloCking elements upon the roller and spindle become engaged at either end of the line of travel of said roller.
